Document Summary
*the nervous system is responsible for everything we think, feel, or do. Central nervous system (cns): the brain and spinal cord. Peripheral nervous system (pns): all nerve cells in the body that are not part of the central nervous system. The pns includes the somatic and autonomic nervous systems. Transmits a variety of information to the cns, which organizes and evaluates that information and then directs the pns to perform specific behaviors or make bodily adjustments. The systems are anatomically separate but their functions are interdependent. The brain is a collection of interacting neural circuits that have accumulated and developed throughout human evolution. Through the process of adapting to the environment, the brain has evolved specialized mechanisms to regulate breathing, food intake, sexual behaviours etc, and sensory systems to aid in navigation and assist in recognizing friends or foes. Everything we do is accomplished by the brain and for more rudimentary actions, the spinal cord.
